There seems to be an obstacle (a facility or unbuildable area) blocking one of the roads (make sure you do not select any roads that would cross other facilities or borders). The road in question is at 21, 19

Umm, press the Print Screen button on your keyboard (should be just above the End, Page Down/Up keys) and then paste into an image program (paint, photoshop etc) and then upload the image to the internet and paste here.

As for what Ten is saying, when you are chosing the location for where the roads go, you cannot choose a location that is outside the slabbed area - the 1 grid wide border that shows the terrain is sancrosact and cannot be built on, either with facilities or roads, and isn't counted as a road itself. So you still have to include roads elsewhere.
